This paper introduces a holographic augmented reality (AR) system that uses inverse-designed full-colour metasurface gratings, a compact dispersion-compensating waveguide geometry, and AI-driven holography algorithms to create vibrant, full-colour, 3D AR content in a compact device. The system eliminates bulky collimation optics and uses a novel image formation model combining physical waveguide modelling with learned components calibrated via camera feedback, achieving unprecedented visual quality.
